Problem with XCMS

Hi!
I have a problem but I don't know exactly if is related with the integration parameters or with the alignment parameters. I've analyzed samples and I really know that I have two isomers compounds separated by 0.1 min. The problem is that I can't separate it, I think that in the alignment process, the most intense is selected and the other discarded. I've tried to change some parameters but I haven't get the separation. I'm using a UPLC-QTOF from Sciex.
Someone who can help me?

Thanks
